What cracked the laughter between the most powerful man and the richest man in the world? I don’t know, wasn’t there, but here is my opinion. Did you expect any less?

U.S. President Barack Obama has been known to crack a joke or two, even take one at times.

So, I can see this happening, in typical Obama style: “Hey, Pope, did you hear the one about…?”, which got both cracking up in laughter.

Remember, this is not the first time the two men have met, and could be they have some recurring joke going on.

Is it unthinkable? Of course not.

I say that because look at the photo of the two back in March 2014 when Obama visited the Vatican.

In that, their first encounter, Obama told the Pope, “if you have a chance to come to the White House, we can show you our garden as well,” Obama said.

“Of course,” the Pope replied.

And there they were this morning.
